According to a study published yesterday in the Nature Climate Change journal, the capacity of terrestrial ecosystems to absorb carbon dioxide (CO2) increased between 1994 and 2014. The study highlights the need to protect tropical forests, as their carbon sequestration rate has risen more than that of any other type of forest over the last few years.
“With the urban population set to grow by 56% by 2050, we need to make cities greener to protect biodiversity”4 de May 2018Verónica Couto Antelo
We interviewed Yolanda Melero, holder of a PhD in biology, whose studies have revolved around the behaviour and dynamics of American mink populations. At CREAF she is continuing to investigate how animal populations function, but is now focusing on butterflies to learn about biodiversity-friendly city design.
A new study led by Josep Peñuelas and published in Nature Ecology and Evolution reveals that CO2 abundance in the atmosphere no longer has a powerful fertilizing effect on vegetation. The greening that has been observed in recent years is slowing and this will cause CO2 levels in the atmosphere to rise, thus increasing temperatures and leading to increasingly severe changes in climate.
Since 1982, Earth has become greener in an area covering 36 million km2, close to two times the size of the United States. Above all, this seems to be the result of a fertilizing effect of atmospheric carbon dioxide (CO2) on plants. The study was carried out with satellite images which can capture this increase in terrestrial leaf area.
